7. Maintenance
Preventative Maintenance.
A careful inspection of your Tube-Ice
machine for leaks and correct
operational functions at the time of installation and start-up will begin a long, satisfactory life of
service. In order to insure this degree of dependability, a systematic maintenance program is
necessary. Therefore, the following schedule is suggested as a minimum.
A.
Daily
1)
Check operating pressures (suction, discharge, oil).
2)
Check ice quality.
3)
Check “ice out” time (maintain 30 seconds of continued harvest after last ice is out).
4)
Check compressor oil level.
5)
Check refrigerant operation level.
6)
Check frost pattern on freezer shell and oil trap.
7)
Check make-up water float valve adjustment.
B.
Weekly (in addition to daily checks)
1)
Check for leaks after 400 hours or four weeks of operation
C.
Monthly (in addition to weekly checks)
1)
Check calibration and operation of all controls (high and low pressure switches, oil pressure
switch, etc.)
2)
Check cooling tower spray nozzles and pump suction screen for scaling and algae (consult
water treatment suppliers for corrective measures).
3)
Check water distributors in freezer for scale accumulation.
4)
Check water tank for solids to be removed.
5)
Check all motor drive units (compressor, cutter and pump motors, cooling tower fan, and
pump, etc) for abnormal noise and/or vibrations.
6)
Check oil level in gear reducer.
7)
Check one complete freeze/thaw cycle, record data and compare with production check of
Registration/Start-up Report.
D.
Yearly (in addition to weekly and monthly)
1)
Check entire system for leaks.
2)
Drain water from condenser and cooling tower and check condenser tubes. Check closely
for damage by corrosion or scale.
3)
Remove all rust from all equipment, clean, and paint.
4)
Check all motors for shaft wear and end play.
5)
Check operation and general condition of all electrical controls, relays, motor starters, and
solenoid valves.
6)
Check freezing time, ice release time, and ice out time.
7)
Change oil in gear reducer box once a year.
8)
Lubricate compressor motor bearings.
